Which type of cloud service model is primarily focused on providing virtualized computing resources over the Internet?

The correct answer is centered around Infrastructure as a Service (IaaS), which is specifically designed to offer virtualized computing resources over the Internet. IaaS provides foundational cloud resources like virtual machines, storage, and networks that can be easily scaled according to the user's needs. This model allows organizations to rent IT infrastructure—servers, virtual machines, storage, networks, and operating systems—on a pay-as-you-go basis, enabling them to avoid the complexities of managing physical hardware.

With IaaS, users have control over their computing resources, leading to flexibility and efficiency in managing workloads. They can quickly deploy and manage virtual servers, which can respond to varying demand levels, making it a suitable option for cloud-based applications and services that require robust infrastructure support.

In contrast, other service models like SaaS (Software as a Service) primarily deliver software applications over the Internet, eliminating the need for users to install and run applications on their own computers. PaaS (Platform as a Service) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching apps. DaaS (Desktop as a Service), on the other hand, offers virtual desktops to end-users,
